Abstract
1,2-Dichlorobenzene is generally used as a chemical intermediate for making agricultural chemicals primarily herbicides, 1,3-dichlorobenzene is used as a fumigant in insecticides and 1,4-dichlorobenzene is used as a space deodorant, moth repellent, and as an intermediate in the synthesis of certain pesticides, dyes and resins. Chemical waste dump leachates and direct manufacturing effluents are reported to be the major source of pollution.
Dichlorobenzene (DCB) was first evaluated by the Environmental Criteria and Assessment Office (ECAO), Office of Research and Development (ORD), Cincinnati, OH in 1987 for non-cancer and cancer endpoints. It was also evaluated by IRIS in 1996 (inhalation RfC; 1,4-DCB), 1992, 1990 (carcinogenicity and oral RfD respectively; 1,3-DCB), and 1991 (carcinogenicity and oral RfD; 1,2-DCB).
